Description

REFERENCE TO RELATED APPLICATION

The present application claims priority from, and incorporates by reference, U.S. Provisional Application Ser. No. 60/457,484, filed Mar. 25, 2003.

GOVERNMENT INTEREST IN THE INVENTION

The present invention was developed partially with government support under a Small Business Innovation Research Program Grant. The government has certain rights in the invention.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to pillboxes and, more particularly, to a pillbox that can be attached to a portable electronic device such as a cellular telephone or personal digital assistant.

2. Description of the Prior Art

Pillboxes in a wide variety of sizes and shapes have been known for many years. See, for example, U.S. Pat. Nos. 4,372,445; 4,640,560; 5,740,938;and 6,082,544. Unfortunately, as shown by the referenced patents, pillboxes often are large, cumbersome objects that are difficult to transport conveniently.

Recently, portable electronic devices such as cellular telephones and personal digital assistants have become widely available. For convenience, any such device will be referred to herein as a “PED.” PED's purposefully are compact and portable, and usually are carried by their owners at all times. However, PED's are used only for such purposes as aural communication, mathematical calculations, and so forth. While the device shown in U.S. Pat. No. 6,107,911 discloses a self-contained programmable time interval alarm for medication administration, the device is large and unwieldy. More specifically, the device employs a housing that employs a clamp with two jaws to accommodate the neck of a medication container. Desirably, a pillbox would be available that could be attached to a PED and carried therewith. Any such pillbox hopefully would be compact, inexpensive, and readily usable.

SUMMARY OF THE INVENTION

In response to the foregoing concerns, the present invention provides a new and improved pillbox that can be attached to and carried with a PED. In one embodiment, the invention comprises a generally cubic body portion that is attached to one end of a PED. The body portion defines a compartment within which medication such as pills can be disposed. It is expected that the compartment will have rounded inside corners that will make removing pills easy and which will prevent pills from getting stuck in the corners. Preferably, an extension projects from one wall of the body portion and the extension is connected to the PED. The body portion preferably conforms generally to the shape of the PED. A door is connected to the body portion to permit selective access to the compartment.

Other embodiments of the invention include a holster within which the PED can be inserted. Various forms of a medication-holding compartment are provided. For example, the body portion in some embodiments has a generally flat wall. A door defines a medication-holding compartment. The door interacts with the wall to selectively open and close the compartment. In all of the embodiments, it is expected that the pillbox according to the invention will be compact, readily usable, and capable of being manufactured quickly and inexpensively, preferably in a plastics molding operation.

The foregoing and other features and advantages of the invention will be apparent from the following description and claims, taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-7, a pillbox according to the invention is indicated by the reference numeral 10. The pillbox 10 can be used with a PED 12. Suitable PED's include Samsung Model SPH-i300, Samsung Model SPH-i500, Kyocera Model 7135, Palm One Tungsten E, Palm One Tungsten W and numerous others. It is possible that the pillbox 10 could be manufactured as part of the PED 12, although it is more likely that the pillbox 10 will be manufactured separately from the PED 12 and used as an aftermarket attachment.

The pillbox 10 includes a body portion 14 that fits on the top of the PED 12. The body portion 14 includes a top wall 16, a bottom wall 18, opposing side walls 20, and a rear wall 22. The interior surfaces of the walls 16, 18, 20, 22 define a cavity, or compartment 24 within which medication such as pills or capsules can be placed. As used herein, the terms “medication” or “pills” are intended to refer to tablets, capsules, pellets, or any other form of medicine or food (such as candy or breath mints) that can be ingested by a human being. The intersections of the walls 16, 18, 20, 22, are rounded, particularly at the corners, in order to prevent pills from becoming wedged or otherwise stuck in the compartment 24.

A door 26 is connected to the forward edge of the bottom wall 18 by a hinge indicated at 28. The door 26 completely covers the front of the compartment 24 when the door 26 is in the closed position as indicated in FIG. 1.

A connection between the body portion 14 and the PED 12 is provided. The connection includes a pair of loops 30, 32 that extend laterally from the bottom wall 18 near the intersection with the side walls 20. The loop 30 fits about an antenna 34 included as part of the PED 12, while the loop 32 fits about a stylus 36 included as part of the PED 12. A generally rectangular extension 38 projects from the bottom of the rear wall 22. The extension 38 is connected to the upper, rear portion of the PED 12 by means of hook and loop fasteners 40 (FIG. 7).

In the illustrated embodiment, the body portion 14 and the extension 40 are configured to closely match the shape of the portions of the PED 12 with which they are in contact. It is expected that the pillbox 10 will be manufactured from a plastics material such as ABS or a similar material in a molding operation. It is possible to manufacture the pillbox 10 from a more flexible material that could be molded to the shape of the PED 12 after it has been positioned in place on the PED 12. While a hook and loop attachment has been described, the extension 38 can be adapted to engage slots or protrusions on the rear of the PED 12, if provided. The extension 38 also could be attached by an adhesive layer. It also is possible for the pillbox 10 to be held in place and protected by a wrap-around sleeve, in a manner similar to commercially available PED's.

The embodiment of the invention illustrated in FIGS. 1-7 has a single-chambered compartment 24 with a single hinged door 26. It is possible to provide a multi-chambered compartment 24. For example, there could be four compartments 26 with indications for time of day (morning, noon, evening, night), or seven compartments 26 with indications for each day of the week. If a multi-chambered compartment 24 is provided, either a single door 26 can be used to close all of the chambers simultaneously, or a separate door 26 could be used for each chamber. The hinge 28 can be provided in any of several variations, such as integrated hinges or post hinges. The door 26 can be provided with molded impressions for labels or raised lettering for branding the product or for identifying a particular drug or drugs, manufacturers, or physicians.

The pillbox 10 is intended to provide storage for a daily set of pills and to work in conjunction with alarm software on the PED 12. Preferably, the pillbox 10 is provided with software that reminds the user when to take the medication. The software can be loaded into the PED 12. If a wireless internet connection is available, a physician, drug manufacturer, or medical supply company can provide the user with reminders and/or information about the medication that should be taken by the patient and a schedule for taking the medication.

The body portion 14 is shown as being of a generally cubic shape. The shape of the body portion 14 can be changed to other shapes, if desired, although it is expected that a cubic shape will be preferred for reasons of appearance and functionality.
